The invention belongs to the field of biogas decarburization, and discloses a device and a system used for separating carbon dioxide in biogas decarbonized solution. The device comprises a separating tower (1), an atomizing device, a decarbonized solution collecting device (3), and a first pipeline (4) and a second pipeline (5) used for communicating the separating tower (1); the first pipeline (4) is used for injecting a rich solution of the decarbonized solution into the separating tower (1), and the second pipeline (5) is used for collecting the decarbonized solution, and is arranged at the lower part of the separating tower (1); the atomizing device and the decarbonized solution collecting device (3) are arranged in the separating tower (1); the atomizing device is capable of atomizing the rich solution of the decarbonized solution in the separating tower (1); the separating tower (1) is communicated with the outside world so as to discharge carbon dioxide separated from the rich solution of the decarbonized solution. The device is capable of separating carbon dioxide from the rich solution of the decarbonized solution, and increasing carbon dioxide separation efficiency.
Description
technical field [0001] The invention relates to the field of biogas decarbonization, in particular to a device and system for separating carbon dioxide in a biogas decarbonization liquid. Background technique [0002] After the biogas decarbonization liquid is used to decarbonize the biogas, the carbon dioxide in the biogas will enter the biogas decarbonization liquid to form a saturated solution. Currently, the commonly used decarbonization liquid is a propylene carbonate formula solution. Due to its high price, it is generally used Recycle the saturated solution. [0003] In order to recycle the saturated solution, it is necessary to separate the carbon dioxide in the saturated solution from the cannon and the solution. The existing technology is to separate the carbon dioxide by using the principle of stripping through the biogas decarbonization liquid packed tower analysis device, but due to the limited gas-liquid contact area, the carbon dioxide The separation effect i...
